Great video. I have seen countless opinions on how to do break in, and most are based on personal experience, but very few are backed up by data. Sure, engine builders can say they have built hundreds of engines broken in their way and most of them didn't blow up, but like Lake Speed Jr. said, that doesn't automatically mean they were broken in correctly. Thanks for the info!

My VW dealer told me that my mk7 Golf is broken in at factory and that I need to run the revs all over to seat valves and no cruise control for 2k miles. At 74k the car doesn't lose oil and still runs great. I'm trying to remember when he told me to do the first oil change. 10k full synthetic oil changes after that. Cheers

I bought a new 2019 nissan 370Z sport coupe and did oil and filter changes at 500, 1500 and 3,000 miles and then went to normal 3K mile OCIs after that. I broke the engine in gently and so it took longer to break in fully, about 5K miles. At that point my oil consumption decreased to about 1 oz per 1K miles, where it is to this day at 17K miles. I've only used the recommended 5W-30 Nissan ester oil because of its high molybdenum content. My engine is very hard on the oil, with its VVEL mechanism on the intake side of the valvetrain, and I've found that this engine, VQ37VHR, on used oil analysis reports tends to shear down 5W-30 Nissan ester oil to a 20 weight after about 3K miles. This is why I don't push the OCI out any farther. If I ran an oil with a better base stock that could withstand the higher temperatures and pressures generated by the VVEL mechanism I could probably go another 2K miles or so on the OCI.

[@FEGTTTSDH]

I recommended Redline oil, much better than the nissan OIL

[@reginaldsmall3766]

I would use amsoil and amsoil filter. Amsoil can take the heat.

[@beboboymann3823]

Race engines are built differently than engines in our street vehicles. 7;000 rpm to break in an engine is not applicable to street engines geez. The best break in for a street engine.......drive it for a few days 300-400 miles in traffic. Yep the stop and go acceleration will push the rings against the cylinder walls and seat them. Don’t accelerate lightly but don’t floor it away from every light. Half to 3/4 throttle several times during the drive will build cylinder pressure against the rings and seat them. Worst thing to do? Miles and miles of 70 mph interstate driving. Lots of oil splashing up on the cylinder walls but no cylinder pressure on the rings. Result?Cylinder wall glazing and no ring seating.

[@darthbacntildeth7221]

Do you still run for 20 mins or so for first run and dump that oil and switch, or hit the street with the first oil? So much mixed info out there... Thx.

[@harrisonkay575]

Very informative. Iv asked a lot of professionals in the engine department they all said after a few hundred KM the process is complete, if there was an issue you’d know within the first 100km. After that like you said dump the oil then your good to go. My Q is, why do manufacturers like AMG, BMW M, say oh you need to do it for 2000km ? I have heard majority if not all performance engines are run pretty much full bore while there testing engines for a few minutes etc for failures before they marry it to the car..?

[@stevel1475]

I believe run it hard for race engines, as they most likely have more lose tolerances so they can run hot with no problems. For street driven engines follow manuals directions, vary speeds all the time. Do not stay at a constant speed, also change the oil sooner as he says 400 to 500 miles. I would refill with break in or conventional motor oil and change it again after another 500 miles, keep changing till I reach 2000 miles. That's what I would do for my car, sound reasonable? I know Acura NSX fully breaks in their engines at factory. My guess is he is probably talking about Corvette engines run on wide open throttle.

[@KemalDaysal]

Hello, I have a 2005 Renault Laguna 2 1.9 Dci (F9Q 750) (120 HP) that have been rebuilt on Feb 11. Everything has been renewed with new ones except crankshaft, camshaft and piston rods. The reason of rebuilding it was burning oil (350ml / 1000km and blue smoke especially on cold) and high blowby at idle on oil cap. The cylinders has been bored by 0.5mm and new oversized pistons inserted. The car runs fine without any leaks, without any smoke at operating temperature and it's powerful now. Still has a little bit of blowby smoke on pcv valve at idle at operating temperature but i hope it'll be gone when break-in procedure is finished. My concern is, the service put a factory suggested Elf Evol 900 SXR 5W40 "Fully Synthetic" oil as initial oil and then they tested the car without my approval. They even said they redlined it on highway and went to 170 kmh which is contrary to break-in period and initial break-in hours. I researched about the break-in oil and break-in procedures and learned a few things but it was too late to tell them to service. They already done this stage. They didn't know about break-in oil anyway and said "use the oil which is recommended by factory as we did it like this". When i asked them about break-in procedure, they said drive it like you want it, it won't matter... Since rebuilt, i've driven the car for 260 kilometers in 6 days and following the break-in procedures. Not lugging it, not overreving it, not passing 3000 rpm and avoiding full throttle sudden accelerations. I've been avoiding idling it for extended time. I've been using the RPM band widely as much as i can to help seating the rings to walls. In 3rd gear, accelerating smoothly from 2000 to 2800ish rpms then letting the foot off the gas and it drops slowly to 2000 again and repeating it on different gears when driving. Not driving it like a cruise control on same RPM. My question is, should it break in like this with fully synthetic oil which is on the car for 260 kilometers? Should i stay with the synthetic oil inside until i reach 800kms and change it or should i change the oil and oil filter to mineral oil like Castrol GTX Essential 15W40 etc. immediately? I fear to glaze the cylinder walls or rings and can't successfully do the break-in procedure with the synthetic oil inside. I fear to damage the healthy turbo or other components with mineral oil too but the turbo repair is much more cheaper than an engine job which i paid significant amount of money. Is it too late for switching to mineral oil? Are my cylinders have been already glazed and rings wont seat as i fear this to happen? How should i test that? What do you recommend in a situation like this? I was planning to do the first oil change when i reach 800kms after rebuild, then the second at 1300km and the 3rd at 4000km. I just want the engine to have a healthy break-in procedure and have a long life and decent performance. The money spent on oils and oil changes is not that much important. I want to drive this car healthy for 3-4 years, equals to 30.000 or 40.000 kilometers with my recent driving hours. I bought the car at August 2020 and have been fixing the problems caused by previous owner, sadly. I’m waiting for your advice, thank you for reading this and thanks for helping.

Hoping for some clarification... just bought a 2020 WRX with a direct injected 2.0 turbo - the manual and Subaru mechanics say don’t go over 4000rpm and do not use boost or full throttle for at least 1600 km’s (1000 miles). Why would they say that if it’s harmful to the motor when they need to pay out on engine warranty repairs for 5 years!?

[@drakeb6168]

i just bought my mustang ecoboost and have not listened to anything the manual has said about break in at all. I have had one in the past and had no oil leaks. Think its due to how i just go drive my car. With the manual though during break in you will want to vary your RPM so no cruise control for you for awhile

[@FoolsAmongUs]

Is the GM 3.6L considered HP? Or, Lake talked about the Mrs., and stated to just stick with the basic oil change at 500 miles? What do You think about AMSOIL?

[@danielplumley379]

Here's a good question. If I am running a boosted engine ( 2.0t, K03 turbo, max 10psi boost), then do I really need to drive the car to break it in if I am technically creating cylinder pressure with the turbo? For example, upon first start, if I run the engine at around 4,000 rpm then I am probably pushing 5-7 psi of boost. Is this enough "load" and cylinder pressure to bed the rings in? In a naturally aspirated engine you need to put load on the engine to create more cylinder pressure. You would do this by driving the car. With a boosted engine, however, you can create cylinder pressure with boost. I am just curious if I can bed the rings in by just sitting at 5-7 psi of boost in neutral without driving the car.

[@MrKaaz]

@DSPORT, so im about to install a remanufactured 5.3L ls engine into my truck. Bone stock build but I want it to last. The rebuilder provided Lucas break in oil with the engine. Obviously have no access to a dyno, So in the driveway would this be sufficient and safe... 1) upon First startup immediately run up to 2500 rpm in park and keep it there for 20 min straight. 2) stop and change oil/filter, refill with break-in again. 3) then immediately take it out and drive it hard for 10 or 20 miles or so and then continue driving hard for next 500 miles. 4) after 500 miles, change oil over to high quality synthetic. Or is it NOT a good idea to run in park at 2500 rpms upon first start up because in the driveway there's no real way to add sufficient load during that time period? Thx in advance

[@PrimalMiltos]

At 7:30 yes, always change it hot.

[@spokes28]

I have a new 2023 Honda Pilot and at 650 miles I went to the dealer for my first oil change. The service manager told me to wait until the message appeared on the dash to change it. Do you think 5,000 miles is to long to wait?

[@AlexORoark]

I have a 23 Ford F-150 3.5 L powerboost it has 12,000 Mi on it and I broke it in according to the manual. Is there anything I can do to make up for lost opportunity

[@dham99]

Almost all of the performance shops and engine builders I've researched have said to do a change within 20-100 miles after first start (rebuilt engine). Keep moderate load (50-75% throttle at most) varying between 3-4k RPMs mostly, not to exceed that, no cruising/highway consistent runs or very short runs. Not to go WOT/full on until the 500-1000 mile break-in process. Wouldnt this be a bit different for race engines that are designed to fail very quickly and constantly be replaced? A v8 race motor that goes a few hundred or a thousand miles is a lot different than a 2.0l Ecoboost turbocharged engine that needs to last many thousands of miles as well as daily driving for years to come. I'm up there with the start up, get up to temps, check for leaks, make sure you have sufficient oil pressure and coolant temps, and give it anywhere from 50-100 miles and change the break-in oil out.. but doing it again for another couple hundred miles without going WOT and much boost is the general consensus. Why is this subject so subjective? Even manufacturers that sell cars like the new C8's, NSXs, GTRs, etc all say to not rag on the car and do a moderate break-in period for up to 1000 miles before tracking them or drag racing, etc. Not everyone has $8k+ to rebuild an engine every few months because they have hundreds of new engine parts on hand and can rebuild a new one in a day lol

[@K_Nasty]

So id do the same process with my dirtbike as long as i keep it on the stand while this oils in there ? Or just add some to my Lucas 4stroke wet clutch oil ?😅

[@jesse75]

Depends what parts you used. If it's a high mileage built engine, a race engine put together for a season of racing or an engine built for one or two runs. And especially, what rings you used. I've built more than 500 engines. Some of the best engines were the stubborn ones.

[@claudiuslouis8498]

Been looking for information like this for a while now. Next question is, can you analyze transmission oil in the same way and who does that type of stuff??

[@duygukayhanisaskank4915]

YES Claudius Louis...transmission oil can be analyzed in the same way as engine oil. Just make sure you send your sample to a lab that specializes in "automotive engine oils". You can find these online. I'd call a few beforehand & ask your questions. They'll send you a kit to return with your fluid//oil. Keep in mind that the design of automatic & manual transmissions create particulates. Transmissions are not built to the tight clearance tolerances as are engines. Therefore, more "debris" will be found in transmission fluid//oil than in a "healthy" engine. The experts should be able to determine if there is "excessive" wear occurring. Regards, Ben P.S. SORRY this is 2 years late. :-)

[@dsport]

[@Invitingsauce]

A lower viscosity oil removes/moves heat more efficiently but doesn’t “cushion” as well as a higher viscosity. But it’s all dependent on bearing clearance, correct? Tighter clearances need a “thinner” oil to flow faster/more efficiently and bigger clearances need more “cushion” to take up the space properly? Do I have that half way correct? Does a 5w-50 offer more/better “protection” than a comparable 5w-30 once up to temperature ?

[@tangles01]

A 5w-50 with have a higher viscosity at 100 degrees c then a 5w-30. They will both have the same at 0 degrees c (both 5 weight cold). That's a more accurate way to look at the numbers. But that's new. as they additives breakdown with heat cycles, the 50 will slowly get closer to the 30 (because the 30 has less thinning to do to get to the 5w). A multi weight mineral oil will do this faster than a synthetic. My recommendation as a simple back yarder is to select the right oil weight for your clearances, use you pressure gauges to see what the real time pressures are at temperature, and change it more often to maintain it. Always use a synthetic, outside of break in. Simply put with the same amount of use the 5w-50 will be the same viscosity at low temp to but thicker at 100c. If you're clearances are bigger you'll want the thicker oil. At some point though, if you have modern heads with hydraulically controlled stuff, it may be too thick for the top end, this is why OEM oils are getting thinner and thinner, as well as better manufacturing for better matched clearances. Now the fun begins when you get some blow by in a turbo engine runing ethenol, where the fuel physically mixes with the oil an thins it even further... ahhh good times.

[@johnmilner7603]

If the rings don’t seat and it’s consuming oil after several 1000’s of miles, can you refill with breakin oil to help seat them? Would this work for both low tension rings and non low tension rings? Cylinders were plateau finished for quicker breakin per builder.

What is the break in temperature, as he mentioned, Performance engine they built being push to the rev limit on 2nd fill up But they break in with driveline or just bare engine, and what temperature they keep ?

[@billkeisling2907]

I have a 1978 MGB that I just had rebuilt. The mechanic, who is very experienced with these engines, didn’t use break-in oil but Valvoline VR1 20-50 racing oil with zinc. Problem is, I’ve now driven the car 400 miles, and it’s still using about a quart of oil every 200 miles. The mechanic is trying to downplay the problem. I’m worried obviously that there’s a problem with the rebuild. The engine does seem strong. I was going to change the oil to 30W Brad Penn break-in oil and run it for another 400 miles or so to see if the rings seat. My question is, is it to late to hope that the rings will seat with the cylinders with the 30W break-in oil? What do you suggest that I do? How many miles should I expect it to take for the rings to sear and oil consumption to go down?

[@yardbirdcom]

@@mareksumguy1887 Yes, I'm afraid it needs to be rehoned and re-ringed too. The oil use only seems to be getting worse. Took it out yesterday and drove it for 100 miles and it used most of a quart. Obviously there's a problem with the rebuild. The mechanic says he 'sees no problem with the engine.' It now has about 1,300 miles on the rebuild. The mechanic just retorqued the head and re-set the valves this month. He blames the oil consumption problem on the engine sitting in the car outside in his yard and not running for several years while we restored the rest of the car. I'm trying to think what's fair here, but obviously I can't run or sell a car that's getting 100-150 miles per quart of oil. I'm wondering: about how much would it cost these days for a mechanic to rehone and re-reing an engine? Obviously that's not a total rebuild, but the engine probably has to be pulled. I'm thinking I could ask the mechanic if he wants to split the difference, but I don't know a fair price for this. If I took it to another mechanic, what do you think is a fair charge to rehone and re-ring a 4-cylinder MG engine? Thanks again.

[@mareksumguy1887]

yardbird tv this is why it’s better to use newer engines in older cars. It depends on what kind of honing you get done; hand hone or machine hone. Ring around a few machine shops / engine builders to see what they charge. Your mechanic sounds like garbage; either incompetent or a liar or both.

This is great ...I am about to break in a 347 stroker brand new ..My builder has me using 10-40 conventional for diesel engines. Break in, start and run for xx time.

Well he said the zddp needs some heat and pressure to get activated and stick to the metal surfaces, besides 2500 is not that high, I think it's important to fluctuate the rpm a little say from 2000 to 3500, just like after the first oil change when driving avoid constant rpm and I would gradually do WOT only from higher rpm, lugging the engine is bad.

Thank you for the invaluable information. Now I'm concerned about my new 2019 Civic Type R. Followed the procedure I got from Honda. 200-gentle miles with gentle braking to allow brakes to wear in properly. Then progressively increased acceleration and RPM until 600 miles. At 600-miles, I was making three runs on an obscure road, full throttle to redline, to 135-140 mph before running out of room and beginning deceleration. I'm at 1000-miles now and planning a spec oil/filter change tomorrow. I was told that the car must run synthetic from the start due to the temperatures the oil is exposed to in the turbocharger, but don't know if that is true or not. Also, don't know if I can temporarily run break-in oil with a turbocharger, or if I need to. Car doesn't feel as peppy as I thought and getting crappy highway mileage (22-23 mpg). How would you recommend that I proceed from this point? Is it just the spec oil change and then driving as hard as possible as often as possible, or do I need to purchase several filters, some spec oil and break-in oil and follow a process? I'll do whatever is best for the car, whatever offer the best chance to give the engine a proper break-in and to run optimally. Thank you in advance for any assistance you can offer.

The full throttle from start is probably the culprit causing scoring on your bearings, if the ZDDP or whatever the break-in compound has not given enough time and temperature to activate on the moving surface. Full throttle is fine if done progressively but not from a complete stop. I would suggest refilling with factory oil and adding extreme pressure additives. They are mostly chlorinated compounds, which smooth out peaks and valleys with heat activation. You just need a low to medium speed and load to break in. When activated, they form a durable iron-chloride surface on moving surface, which happens when you start to feel a smoother idle. Then you should drain the oil because excessive chloride may react with moisture and form a strong acid. Too much Extreme pressure additive may cause bore polishing, an adverse affect you should keep in mind . Good luck!

You only have ONE chance to break in an engine and you blew it…but since it’s a civic, it doesn’t matter

[@anonymike8280]

Anybody in this situation, do what the factory says. It was three years ago. Tell us how it worked out. Maybe the not so peppy performance is how it goes with that engine.

[@nYdGeo]

Well, three years and a little over 40k miles and things already fine. The Civic Type R still runs like a scalded dog on crack. There's a long string of Z-cars, Camaro SS's, Scat Packs and more that have fallen in roll races down in Mexico. I'm no longer stock, about 90 whp and 100 lb ft over stock, same fuel economy, doesn't leak or burn any oil, catch can has drops after several thousand miles. It's good. Make several trips each year from S. LA to the NC/TN border area to drive the Dragon, Cherohala...it's an excellent road trip vehicle. Rigid Collar set, Swift Spec R springs, Rotodisc floating rotors, Street Racer pads with titanium backing plates. It's a minimalist build handling wise, but you'd be amazed at the vehicles this vehicle can best on a twisty road.

[@anonymike8280]

​@@nYdGeo Thank you for getting back. Little of this is practical for me but I am working on the topic right now if only to know where I have been already. With contemporary production, the manufacturers say no elaborate break-in is required, perhaps just following certain driving protocols for the first several hundred miles (or kilometers). I have been paying attention to the different theories about break in especially related to piston rings. Some people say, push the engine hard during break in. I have a theory, which is, as the piston rings flex up and down infinitesimally during acceleration and deceleration, the edges of the rings get polished and lapped, or rounded off a little if you want to call it that. If the engine is going to be driven hard during its service life, maybe it is better to push it hard and get the edges lapped a little more. I think a lot of this applies only to older production and especially to rebuilt cast iron block engines. With contemporary production out of the factory, maybe some of these issues do not exist. Another thing I have found out is that in a standard performance cast iron or cast irong lined engine, it make absolutely no difference whether you use cast iron, chrome or moly rings. That's according to Hastings, which makes the rings. I would say, cast iron would be preferred because cast iron rings would be more likely to break in properly. By South LA, I gather you mean Louisiana. I live in the Central Valley of California. We neither think about or go to L.A. the city. Mostly, we want to keep our driver's licenses and we also want to wake up alive tomorrow morning. But the Rams are my favorite NFL team right now. Goes way back in time. I grew up in Chicago but the Rams were a popular team in the 1960s and they were a popular team when they were in St. Louis during the Kurt Warner era too. I'm one of the survivors who saw that game on television where the Rams beat the Packers in the L.A. Coliseum back in the 1960s. If you were from Chicago, any time someone beat the Packers back then, they were your friend forever. Just one more question. Did you eventually conclude that you were getting normal gas mileage for that vehicle for the type of driving?

Hey I just got a new 2019 Camry. It says on the manual that the break in process is for 650 miles. I’ve put about 1400 miles already, should I change the oil for the car now or wait until 5k?

[@ghostface12258]

Will the engine smoke a little during the break in period? I have a little smoke coming out of the exhaust. Is that normal.

[@mr.anonymous3103]

Spencer Williams yes. Every car is different it smoke is to be expected. Just drive it normally and don’t redline the car u til after you do the first oil change. Usually at 5k miles.

[@TurboVisBits]

@@mr.anonymous3103 the line on the dash means nothing. shut up.

[@jsnokhous]

Thanks for the info. I find this very interesting. The concept of running an engine hard when it’s new to seat the piston rings and everything does make sense. My question is why do owners manuals suggest otherwise? For instance on a Corvette the tachometer shows the redline at about 3500 RPM for the first 500 miles to remind you not to go past that point. I just ordered a Ford Raptor with the EcoBoost so I’m researching what fuel to run, motor oils and how to properly break it in. Can you touch on the disconnect between your advice and general manufacturers advice? Thanks in advance!

[@dsport]

OEM engines come to life feeding on natural gas in many cases and they are already "broken-in" with respect to piston-ring-cylinder-wall break-in. Hence, there is no need to break-in the engine with the proper method if it's already broken in. Now while the engine might have been properly broken-in, there may be a loose accessory, fitting or ????? It the driver isn't doing full-throttle blasts from stoplight to stoplight, they have a better chance of finding a rattle or issue before it becomes a major problem. It's also a good practice for someone to get a feel for the car at minimal power before they push it to the limit. Still, there isn't any drawback from following the run-it-hard protocol. Just make sure the engine is at normal operating temps. Wear is significantly reduced on engines as temperatures go up. As for the fuel and oil recommendations. Run the highest octane fuel that you can afford. If you have direct-injection only engines (which I think those are), consider a water-meth system to reduce intake valve deposit formation. Also, use an SN-plus oil or an oil specifically made to deal with LSPI. Check out our video on LSPI to learn more.

[@jsnokhous]

@@dsport Thanks for the detailed response. The new Ecoboost engines have direct and port injection. I'm still going to run a dirty side catch can. And it sounds like I need to run 93 oct.

They are selling the stuff. They would say that, wouldn't they? A non friction modified oil or non synthetic oil is fine. It is how you run the engine at break in that determines the outcomes, if this is done incorrectly , no oil will hide it.

That is good advice for the rings, but bad advice for the bearings. Racers flog the engine kuz they know their bearings are coming out before 25,000miles let alone 250k. Yes change the initial oil fill at 3-500 miles. No to beating the sh*t out of bearings which are still wearing in.

[@DivergentDroid]

@@reginaldsmall3766 You use a magnet to trap the particles. Even then you won't get them all but way more than without. Look up videos on using magnets for this. Install a good filter too! You see, you can drain the oil but while the heaviest particles fall to the ground they will stay in the engine all over the inner surfaces. A magnet will catch More not All. Best thing to do is run 10 gallons of oil and gas through the system and catch/filter all that comes through under high pressure.. Then do it again! NO ONE doles that. It's physics.. which most wrench jockeys don't understand. Also, they are Cheap.

I didn’t know there was such thing as break in oils. Didn’t think they exist. I figure oil is oil no matter what. But I wouldn’t go by what this guys saying. Break in period, just drive it normally. Why race it and drive it hard? You don’t do that at any time. On occasions, I’m sure there will be a time you’ll naturally go harder. All that freeway driving and constant stop and go in the city, your cars already working hard. Normal cars, normal drivers, just drive normally. Lol. Break in oil change, a thousand miles is perfect compared to 500 miles. In the end, it’s totally up to the driver.

[@nastynate9529]

I feel like these facts are outdated. I spoke to the guys at VW about break-in oil on my new GTI and was told such an oil does not exist, at least not in their engines. They ship it with the same oil they put in at the dealership.

Why drain the oil hot at its thickest viscosity. A 5w30 is at its thinnest cold, at 5 and thickest hot 30 it's made this way for startup, so seems you would drain cold.

The first number, denoted by W, is one viscosity scale. The W stands for Winter and it is one rating system for viscosity. The number represents the viscosity at a standardized temperature. The second number, 30 for example, is a viscosity on the hot scale. A totally different scale and a different specific temperature. Please look it up if you haven't learned better by now.
